" WINDOW CONSTRUCTION;

'Application led.

It is herein pointed vout that said pla-te 25 in no manner interferes with the opening cr closing movement of either sash, noV matter whether said plate is in its open or its closed position.

Suitable coacting parts of locking Ydevices (not shown) may be used between said rails, with one of said parts carried by the plate and the other carried lby the bottom rail of the' top sash.

My improved window construction pro-.

vides a simple and eiiici ent means for providing ventilation Jfor the room in which it is used. The improved window is in no mannerl unsightly in appearance and does not interfere with the use of curtains, shades or screens, therefore, itis as well adapted for use in the home as in oce buildings and the like.

vlliile in describing` my invention I have referred to certain details of mechanical construction'and-arrangement of parts, I do not wish to be limited thereto except as may be vpointed out in the appended claims.

I claim as my invention:

l. The combination with an upper and lower window sash, said sash having rails adapted to meet when the sash are Closed and being spaced apart to provide a ventilation passageway between them, means carried by the lower sash and adapted to be swung to a position to close said passageway or to a position tofully open the saine, said means I including a weather strip member to seal Y said means when in closed position.

2. In'combination with the meeting rails of a pair Voi? window sash which are spaced apart to provide a ventilation passageway between them, a plate hingedalong one gin to one of the meeting rails and adapted to be swung into a position to either open or close said passageway, and a weather stripy carried by the other meeting rail for engagement by the free margin ot said plate when in a position closing said passageway.

3. In combination with the meeting rails of a pair of window sash which arei'spaced apart to provide a ventilation passageway between them, a plate hinged along one margin to one oit the meeting rails and hav ing a liange along its other margin, and a weather stripv carried by the other meeting rail and adapted to be engaged by said flange when said plate is in a position closing said passageway. v

4. In combination with the meeting rails of a pair of window sash which are spaced apart to provide a ventilation passageway between them, a-plate hinged along one mar? gin to one of the meeting rails and adapted to be swung` into a position to eitherv clQse or open said passageway, a. weather strip carried by the other meeting rail for engagement by the other margin of said plate when said plate is in a position closing said pasn sageway, and a second weather strip carried on the underside of said plate and engagingl the first mentioned meeting rail when said plate is in its closed position.

5. In combination with the meeting rails of a pair of window sash which are spaced apart to provide a ventilation passageway between them, a plate hinged along one man A'gin to one ot the meeting rails and having flange along its free margin, a weather' strip carried by the other meeting rail for engagement by said iiange, Yand a second weather strip carried on the underside of said plate for engaging the first mentioned rail, when said plate is in a position closing saidv passageway.

In testimony that I claim the foregoing as my invention, I ajliiX my signaturefth-is 23rd day of May, A. D. 1923.
